The document presents a revised attribute-based data sharing scheme in cloud computing aimed at resolving the key escrow problem associated with ciphertext-policy attribute-based encryption (CP-ABE). It introduces an improved two-party key issuing protocol and a concept of weighted attributes to enhance data confidentiality while reducing encryption complexity and storage costs. Performance analysis indicates that the scheme effectively achieves efficient and secure data sharing in cloud environments.

In this paper, we redesigned an attribute-based data sharing scheme in cloud
computing. The improved key issuing protocol was presented to resolve the
key escrow problem. It enhances data confidentiality and privacy in cloud
system against the managers of KA and CSP as well as malicious system
outsiders, where KA and CSP are semi-trusted. In addition, the weighted
attribute was proposed to improve the expression of attribute, which can not
only describe arbitrarystate attributes, but also reduce the complexity of
access policy, so that the storage cost of ciphertext and time cost in encryption
can be saved. Finally, we presented the performance and security analyses for
the proposed scheme, in which the results demonstrate high efficiency and
security of our scheme.

Data owner is allowed to fully control the access policy associated with his data which to be shared. However, CP-ABE is limited to a potential security risk that is known as key escrow problem whereby the secret keys of users have to be issued by a trusted key authority. Besides, most of the existing CP-ABE schemes cannot support attribute with arbitrary state. In this paper, we revisit attribute-based data sharing scheme in order to solve the key escrow issue but also improve the expressiveness of attribute, so that the resulting scheme is more friendly to cloud computing applications. We propose an improved two-party key issuing protocol that can guarantee that neither key authority nor cloud service provider can compromise the whole secret key of a user individually. Moreover, we introduce the concept of attribute with weight, being provided to enhance the expression of attribute, which can not only extend the expression from binary to arbitrary state, but also lighten the complexity of access policy. Therefore, both storage cost and encryption complexity for a ciphertext are relieved. The performance analysis and security proof show that the proposed scheme is able to achieve efficient and secure data sharing in cloud computing. CONCLUSION
